Database error on update

I am trying to update EE v2.4 to v2.10.1 and got a database error.

Error Number: 1060

Duplicate column name ‘can_search’

ALTER TABLE exp_member_groups ADD COLUMN can_search char(1) NOT NULL default ‘n’

Filename: updates/ud_0_00_09.php

Line Number: 112

I rolled back the files & database to pre-update condition, but need to try again to get the install updated.

Any help is appreciated.
